u lu one practical embodiment of the iti- :entiou each goods containeror carrier is provided with a pair of? Vertiral supporting ern'isconnected by a. cross bar andinounted on a. rocl. shaii' ovided with aorenl. the end ot Wliicli connected to a rod crossing over and extendingupwardly to a point ahead of the if'ertical arms, when the latter is inits raised and normal position7 the outer ends of said cross rod beingconnected to e. counterbal:incing` element ufliieli may conveniently bethe hinged door of the casconteining` the goods. The door is hinged atits top liorizc'antel edge and, as the L ical arm moves radiallyoutwardly, the door lifts radialhv until it 'assumes a horizontal orappresomately horizontal position the travel of the arin and door beingsuoli 1920. Serial ll'o. 373,848.

tlat the latter is olea-r to admit the former Clo serure greaterclearance for the s between the door and the bottoni of easing, portionof the latter may loe hinged and arranged to swing downwardb7 during thefinal raising movement of the door. l/Vhen the door is lowered itoperates the oianlr and reverses the rock shaft thus returning the armssupporting the goods rWithin the easing. lf it is desired to -lofer thegoods closely to the tace line oi' the oasing, the supportio arins areformed of suit ably jointed n'ieinbers as hereinafter ex plained.

lf preferred the erank .may be connected to a spring controlled slidabloelement in such a manner that the lowering oit the goods or casingcontaining saine puts the spring in compression, the power of which isutilized to return the goods or casingto storage position therebyrendering the operation of raising the goods easy of manipulation,

The construction illustrated in the accompanying drawings constitutes apractical i'orni oi' the invention.

Fig. 2 is a horizontal section approxi.- inately on line 1.1 of Fig'. 1broken.

Fig'. 3 is a horizontal section through the upper portion of the gearcompartment.

Fig. l is an outline elevation of two of such casings (with the gearomitted) showing in' one instance the goods in loweredposition.L

Fig. a. fragmentary detail illustrating .iuodilication of the supportingarms.

Fig. 6 is a Vertical sent-ion and f7 a horizontal section partly brokenillustrating another forni of the invention height and near the bottomof saine is e e with parts horizontal roel; shaft l, the ends of whichare journalled in bearings 2, 2 in the Asides of the casing,

Fixed to said shaft are vertical arms 3 to each of which is pivoted alever .l pivoted at its lower end to a link 5 the lower end of which ispivotally mounted on lug 6 fixed to the floor of the casing. The upperends of the levers el. are joined by a transverse horizontal bar 7 whichis used to either afford direct support for the goods or containers forsame.

Project-ing from the shaft l at one end is a crank or offset arm 8connected by a cross over rod 9 with the upper portion of the door Dhinged at the upper end as at l0 to the easing. Thus, when vthe rockshaft l is partially rotated by any suitable means, the door opens andthe supporting' bar 7 descends out. of the casing tothe position closeto the face of the casing as shown by broken lines in Fig. 1 and in fulllines Fig. l.

rIhe weight of goods and the supporting bar 7 is approximatelycountcrbalanced by the gravity action of the yhinged door in de-rscending so thatv reverse rotation vof the shaft l is-easy ofmanipulation.

lf it is desired to lower the goods to a position some distancein frontof the casing, as for instance above a shop counter, the levers 4 andlinks 5 are dispensed with and supporting arms such as 3 in Fig. 5 areemployed.

One practical means shaft l and locking same'in desired position isdepicted in Figs. l, 2, and 3 of the drawings. herein the upper end ofthe door is provided withv au arm 'll inwardlyv project` ingapproximately at right angles from about the hinge l0, said arm beingsupported by a brace l2 and having at its end a pulley ll. These partsare enclosed within the gear compartment G formed at one side of thecasing by a partition P. At a suitable position within said compartmentis a tilting bracket 18 mounted on a pivot 19 lined on the casing walland provided with Vtwo upwardly extending projections 2O bearing againstthe underside of a pivotedloclting bar k21 controlled by spring` andstops .3s and Vhaving ato'oth "at its end adapted to vengage with 'oneof a series of teeth formed on a quadrant Wkeyed to the shaftl.Saidbraclret ,i8 has also tw'oopp'ositely extending arms ,l/:l 'and l5supporting pulleys 16 and 17. v

A cord 24 is fixed at one end25 tothe casing and passes up over pulley13 and around a vpulley 25 fixed tothe casing ne'arsaid end Q5, saidcordlthen passing-aroundthe inner side of pulley 16 at'the sideof-aguide pulley 27 and out throughan aperture formed iii-the bottomofthelcasing. The'cord-then loopsbaclr past guide pulleyQS, aroundgpulfor operating theV ley 1T and upwardly over a fired pulley 29 andunder another pulley 30 mounted on an arm 31 extending upwardly from therock shaft l, the end 32 of said cord being nxed to the casing near thepulley 29.

At will be understood that by grasping the lower hanging portion of thecord 2lishown nearer the front of the casing and pulling in a downwarddirection the bracket 18 is tilted and one of the projections Q0 liftsthe locking bar 21 and consequently its tooth out of engagement with theteeth of the quadrant 23 which is thus released.

The pulling operation of the cord Q-l draws ydown arm l1 and opens thedoor D whereby rod 9.oonnected to the crank S roc-lts the sha-ft l andlowers the bar 7 and the goods Y supported thereby.

As shaft l rotates forwardly arm 3l swings over and. draws up the cordover pulley 29 and similarly arm 11 performs the same function on therearward rotation of the shaft which is 'similarly effected by pullingon the other portion of the cord.

In lieu of the cords 2d, arms ll and ill, brace l2, `locking bar 2l, andbracket 1S, a worin 6() (Fig. 9) may gear with the toothed ruiadrant 23,the shaft 6l of said worm being mounted in bearings 62 projecting fromthe side ofthe casing and it is provided with a pulley 63 operated by acord Gil or said sha-ft may extend through the front of the casing andbe provided with a crank handle 65.

The forward portion of the bottom of the ease may bel in the formi of aiiap hinge( at its inner' end at 36 and provided with lugs 37 eachhaving a pivot 38 on which is mounted an arm 3S) formed with alongitudinal slot i0 engaged by a pin di on the vertical arm 3. Thus,when said arm operates the pin al slides in the slot till it reaches thelower end thereof when it causes the viap to swingdown as illustrated inFig. l. Similarly on 'the the return of the goods to the case, the

flap is operated during the nal movement of the door D to close at itsouter end against the lower end of said door, said ends being bevelledtoensure a good dust proof j unction. It will be evident, however, that inif lieu of this construction the flap Si) in be integral Witlithe doorin which ease 'mechanism just described would Vbe nimeer-s saryAccording to the "form of the invention shown in Figs. 6 and `7 thecontainer S is mounted onthe supporting arms 3 to swingbodily out of afixed frame 42 and it is lprovided with drawers i3 to contain the goods,

'said drawers being drawn out from the side of the container when inlowered position as indicated inbreken lines VFig. 6.

he crank 8 iscentrally arrai ged on the shaft l and is providedvwith across yhead fdllkfornied with lugsy tofeach of which is fixed CIK pas

one end ot a cord 45. Beneath the crank is a base plate 46 havingthereon a slide block 4T and a slide nut 4S with a spring 56 betweensaine, said nut 48 being in screwed engagement with the threaded end ofa screw 49 the shank oit which passes ireely through tho block 47 andthrough a lug on the base and is provided with a handle 50 for rotationoit said screw. Mounted upon lugs formed on the base are pulleys 5l, 52and similar pulleys 53, 54 are provided on the block 47. One cord 45passes down under pulley 51 and up over pulley 53 and then back to ancnd lug 55 to which its end is attached. Similarly the duplicate cordpasses around pulleys 54 and is fixed to lug 55. Thus, when crank Srises by rotation oi rock shaft l. slide block 47 travels along the base46 and compresses the spring 56 as the container S is being lowered toposition shown in vbroken lines in F ig. 6 and the stored power of thespring is used to lift the container back to its normal position in thetrame 42.

By rotating the handle 50 the tension of the spring' 56 can be adjustedto nicely counterbalance the weight of the container so that ease ofmanipulation is assured.

In the form illustrated the container is provided with a handle H forraising and lowering and locking same and the case is supported 'fromthe top upon bars 57 pivoted at their lower ends to lugs 58 on theiframe, said bars having' parallel action with the supporting arms 3 toensure the show case maintaining its vertical disposition while beingraised or lowered.

Means for locking the shatt may be employed, it desired, in connectionwith vthe torni oit the invention just described. A practicalconstruction is shown in Fig. 8 and consists ot a toothed quadrant 23Lmounted on the rock shattlbetween its centre and one end and a pivotedlocking bar 21 having a tooth 22 engaging the quadrant, said bar beingcontrolled by a spring 66 and connected at one end with a cord 67 passedover a pulley 68. By pulling' the cord the locking bar is released froma tooth oi the quadrant which permits the rock shaft l to be rotated andthe container S to be lowered or raised.

it is to be understood that the apparatus described is applicable forlowering goods, either suspended V troni the supporting bar by means torinstance, as iixed and swivel hangers or stored in containers, shelves,cases, baskets, and the like sup-ported thereon, and it is alsoapplicable for bodily lowering an entire show case with or withoutdrawers or the like.

Moreover, in the constructions illustrated two vertically disposedsupporting arms are shown for each case, but it will be evident that asingle arm might be employed with a cross bar for supporting the goods,also that a crank might be formed .integral with an arm and the wholekeyed to the rock shaft or the arm crank and quadrant might be formedintegral and swing on a iixed shaft.

Furthermore, it will be evident that where a number of show cases arearranged one beside the other a rock shaft might be extended through aseries ot cas-es and the goods therein simultaneously raised and loweredby a single manually or power operated device controlling the rota-tionofthe rock shaft.

It will be evident that the rock shaft may be rotated by other meansthan those illustrated and that the goods on the supporting` element asdepicted in Figs. 1 4 may be lowered and raised by opening and closingthe door of the casing.

Furthermore, either of the arms ll or 3l may be cord operated forraising and lowering the goods and the goods may be raised by closingthe door. y

It the case is not fitted with a door a counterbalancing weight may besuspended from the outer end of the crank or a projection on thesupporting arm and the rock sha-ft rotated by any suitable manual orpower operated means.
